The researches on saliency detection for common images have been thoroughly explored in recent years, but little attention has been paid to hyperspectral images. However, salient region detection can contribute to finding significant targets in hyperspectral images. In this paper, spectral saliency is introduced to the spectral domain for detecting targets in hyperspectral images, which are computed by expanding the Itti's visual attention model. Firstly, spatial and spectral features are extracted from hyperspectral image. The conspicuity feature of the first three principal components, orientations, spectral angle and visible spectral band opponent are computed to sum into a saliency map. Finally, salient targets are detected by winner-take-all strategy finding the region with the highest value in the saliency map. Experimental results show that the proposed method have better effectiveness of target detection compared with the method based on RGB image and visible spectrum.

The joint maximum likelihood sequence estimation (JMLSE) is a useful algorithm for the single-antenna co-channel interference cancellation. But the conventional JMLSE algorithm is only suitable for continuous signal. If burst signals are processed as continuous signals, the conventional JMLSE will suffer an error floor. To overcome this problem, a modified JMLSE algorithm was proposed for burst digital signal. Simulation results show that the proposed algorithm can eliminate the defect of error floor, and the performance is almost the same as continuous signalprocessing.

We present a scheme for the practical decoy-state quantum key distribution with heralded single-photon source. In this scheme, only two-intensity decoy states are employed. However, its performance can approach the asymptotic case of using infinite decoy states. We compare it with the standard three-intensity decoy-state method, and through numerical simulations, we demonstrate its significant improvement over the three-intensity method in both the final key rate and the secure transmission distance. Furthermore, when taking statistical fluctuations into account, a very high key generation rate can still be obtained even at a long transmission distance.
In RFID systems, one of the problems that we must solve is the collision between tags which lowers their efficiency. Two main approaches to tag collision are generally adopted: ALOHA and Tree algorithms. This paper re...

Multi-antenna blindsignal separation (BSS) provides a useful method for co-channel mixed signalprocessing. But the performance of BSS is limited by the condition number of channel matrix in the presence of noise. To overcome this problem, a new BSS algorithm with the aid of lattice reduction (LR) is proposed for synchronous communication systems. Simulation results show that the proposed algorithm improves the symbol error rate (SER) performance in noise environment while keeping the same complexity level.
